Right Image Builders is a licensed and insured Florida general contractor (CGC1539321) in Oviedo, building home additions and ADUs across Sanford and Seminole County. Room additions, second stories, in-law suites, and garage conversions — structural engineering, permitting, and construction under one contract. 4.9★, 433+ projects.
Adding on is the most structural work a home can undergo — foundation, framing, roofline, and tie-ins all have to be engineered and permitted correctly. We manage the whole process, from feasibility and design through permits and final finishes.
Additions and accessory dwelling units (ADUs) are handled differently by each jurisdiction — the City of Oviedo, unincorporated Seminole County, and the City of Orlando each set their own rules. We build to what actually applies to your Sanford lot.
Add a bedroom, primary suite, or great-room bump-out with a foundation and roofline that match the existing home.
Build up when you can't build out — engineered for the existing structure and Florida wind loads.
Detached or attached accessory units and garage conversions for multigenerational living or a home office, built to local code.
We coordinate the structural engineering, permitting, and any HOA/ARB review so the addition is legal and lasting.
We work throughout Sanford — from Historic Downtown Sanford and Lake Forest to Celery Estates, Markham Woods, Mayfair. Sanford is the Seminole County seat, with a historic riverfront downtown and older housing stock, and it sits in Seminole County, part of the Greater Orlando area we cover from our base in Oviedo.
Permitting for a Sanford home addition goes through City of Sanford Building Division. Parts of Sanford carry historic-district review, so anything that changes the look of the house from the street can need an extra approval before a permit is issued. We build that step into the schedule rather than discovering it late.
Alongside Sanford, we regularly take on work in nearby Seminole County communities including Winter Springs, Casselberry, Longwood and Lake Mary.
Every Sanford home addition we take on is run by the same licensed general contractor (CGC1539321) that pulls the permit — so there is one point of accountability from the first walkthrough in Historic Downtown Sanford or Lake Forest through final inspection with City of Sanford Building Division.
Sanford is the Seminole County seat, with a historic riverfront downtown and older housing stock.

These are typical planning ranges — not a quote. Every project is priced after we see the space. Permit and inspection fees charged by City of Sanford Building Division are separate and vary by scope, and we itemise them for your Sanford estimate rather than burying them in a lump sum.
